How do I throttle button taps in Combine with Swift?

Throttling button taps in Combine with Swift can help to avoid multiple rapid-fire actions, improving the overall user experience by ensuring that events are handled smoothly and efficiently.

Here’s an example of how to implement throttling for button taps using Combine in a SwiftUI application:

import SwiftUI import Combine struct ContentView: View { @State private var buttonTappedCount = 0 private var cancellable: AnyCancellable? var body: some View { VStack { Text("Button tapped \(buttonTappedCount) times") .padding() Button(action: { // Action performed on button tap }) { Text("Tap Me") } .onTapGesture { handleTap() } } } private func handleTap() { if cancellable == nil { // Create a throttle effect for button taps cancellable = Just(()) .delay(for: .seconds(1), scheduler: RunLoop.main) .handleEvents(receiveOutput: { _ in buttonTappedCount += 1 cancellable = nil // Reset the cancellable after the action }) .subscribe(on: RunLoop.main) .eraseToAnyPublisher() } } }
